Rework P4Ruby unit tests so they they are actually units. Now the
test order is irrelevant as all tests are standalone. Tidied up
the code formatting as well and removed all the tabs from the ruby
sources files. Added a modeline for vim users so consistent
indentation will be used.

Fix unlink error on unit tests
Wrap the connect/disconnect in begin/ensure blocks to
ensure that the client disconnect even if there are failures
in a unit test.

Fix unicode unit test for 1.9. When the contents of a file
is stored in a String object, ruby 1.9 sets the String's
encoding to the current locale. This is overridden in the
test case and set to the correct value. This may need to
be documented.
